The negative effects of global warming are increasing worldwide and this increase is expected to continue. The camelina plant, which can be grown in marginal areas, stands out among other oilseed plants because it is drought-resistant and less costly. In the research, seeds belonging to 8 camelina genotypes, which were prominent in terms of oil rate, seed and oil yield, were used in the trial established in Bolu province, out of a total of 52 genotypes obtained from the seed bank of the United States Department of Agriculture, Agricultural Research Service and Germany. The study was conducted according to the Randomized Complete Block Design in Bolu Abant İzzet Baysal University, Faculty of Agriculture, Research and Application Field in the 2021-2022 production season. In the trait, each plot consisted of six rows with a row length of 3 m, a row spacing of 20 cm, and in row of 5 cm, with three replications. According to the research results; plant height 66.33-71.00 cm, number of branches 3.17-5.07 number plant-1, 1000 seed weight 1.10-1.24 g, seed yield 1095.4-1436.6 kg ha-1, oil content 36.63-40.37%, protein content 23.65-27.22%, oil yield 408.3-559.8 kg ha-1 and protein yield 279.0-391.3 kg ha-1. It was found that values between. According to the results obtained from the study, the K52 genotype in terms of seed yield, the K11 genotype in terms of oil rate and the K52 genotype in terms of protein rate came to the fore.

Black cumin (Nigella sativa L.) is one of the essential spice plants used in Turkey. The present study investigated the yield and some agronomic, morphological, and qualitative characteristics of 31 different black cumin genotypes (30 lines and one control variety of Çameli) of domestic and foreign origin under the ecological conditions of the city of Ankara. The study was carried out in the experimental areas of İkizce Research and Application farm of Ankara Field Crops Central Research Institute during the vegetation periods of 2018-2019. The experiment was set up as three replications according to the Experiment Design in Randomized Blocks. According to the results of the research, the plant height of the genotypes in the experiment changed for two years between 17.1-33.5 cm, the height of the first capsule between 11.6-26.6 cm, the number of seeds in the capsule between 28.5-69.6 seeds capsule-1, the number of branches between 2.0-3.4 pieces plant-1, the number of capsules between 1.8-2.9 capsules plant-1, thousand seed weight between 2.0-3.0 g, seed yield between 194.5-505.9 kg ha-1, fixed oil rate between 27.2-35.3%, maturation (growth/harvest) time between 136.5-141.7 days and germination (emergence time) between 27.2-30.7 days. In terms of fatty acids, the most proportional fatty acids were found to be linoleic acid (45.45-55.62%), oleic acid (18.83-25.01%), palmitic acid (6.95-11.72%), stearic acid (3.50-4.77%), respectively. It has been determined as the result of the study that black cumin genotypes with the number 1 (Denizli), 4 (Burdur), 17 (Borsa) and 3 (Burdur) respectively performed better than other black cumin genotypes and Çameli variety in terms of seed yield and genotypes with the number 28 (Kırıkkale), 29 (Ankara) and 26 (Egypt) performed better in terms of fixed oil ratio under the ecological conditions of Ankara.

This study was carried out to determine the effects of different harvest times (ontogenetic and diurnal variability) on the yield characteristics, content and composition of essential oil in summer savory (Satureja hortensis L.) in 2014 and 2015. The experiments were conducted at the experimental fields of the department of field crops, Faculty of Agriculture, Eskisehir Osmangazi University using a split-plot randomized complete block design with three replications. According to this research results, values of dry herb yield, dry leaf yield, essential oil content and essential oil yield ranged from 2.11-3.26 t ha"1, 2.07-2.79 t ha"1, 2, 55-3, 73% and 56.89-93.57 1 ha"1, respectively. Carvacrol, the first main component of the essential oil, ranged from 49.71 to 54.75%, while y-terpinene, the second main component, changed from 28.03 to 34.58%. Considering the dry leaf, essential oil yield, content and components, the harvest in 40-60% flowering period and at 12:00 pm for the cultivation of summer savory in Eskisehir ecological conditions can be suggested.

Carthamus L. (Asteraceae) has been used in many secto rssuch as food, dye, cosmetic, biofuel industry and also used to cure many disease in traditional medicine. Within this study, it was aimed to present detailed anatomical characterization of five wild species of Carthamus grown in Anatolia, namely, C.dentatus Vahl., C.glaucus Bieb., C.lanatus L., C.persicus Willd. and C.tenuis (Boisand Balansa) Bornm. And to contribute to botanical and agricultural studies. Free-hand sections were taken from root, stem and leaf of each taxa. Sections were examined with light microscope and photographed by digital camera. Various measurements were taken on microscopic images. Variations on collenchyma to us cells in cortex, arrangements of scelerenchyma to us cells in vascular bundles, type of vascular bundles and state of the piths in stem; cuticular ornamentation, leaf types based on their adaxial-abaxial and crystal lines tructures in leaves were observed. Furthermore, an identification key was given based on anatomical features. Although anatomical features were generally similar, some of the characters varied among the species. According to the anatomical properties, C. persicus and C. glaucus were closely related to C. dentatus and C.tenuis, respectively, whereas C. lanatus was quite different from the others.
